Application filed November This invention relatestomachines forironwhich extend toward each other beyond the \55 ing the toes of shoes,and an object of the invention is to provide a machine for use in themanufacture of shoes, whereby the folded edges of the shoe parts may besmoothly pressed and adhesively united with greater ea'se,'rapidity and"less cost than by present practices. I i

Another object of the invention is to provide a machine for ironing,smoothing and pressing the in-folded lower edges of the shoeuppers toformsmoothsurfaces so that, 1 when the shoe is'c'ompleted by theattachment of the sole, no grooves,.openings orinterstices ment ofthisresult, provisionis made forfthe adjustment of the machine for work uponshoes of different sizes.

Various other obj ects of the invention will appear from the followingdescription, refer- 'ence being made to the drawings, in which Fig. 1 isa front elevation of my improved machine. Fig. 2 is a side elevation.

inner walls of the slot 7 so that the space between theinner edges oftheflanges 8 is of narrower width than the'width of the slot 7 (Fig. 5).A bolt 9 extends through the slot 7 and through a hole in the frame top4 and with the nut 10 constitutes a clamp for securingand' holding thepart 5 in rigid position andpermits the art 5 to be secured-in selectedadjustmen s. as required to accommodate shoes ofidiiferent sizes. 4 Ablock 11- has a pair of laterally projecting trunnions 1 2 seated in.notches in the standards 6 and a gripper-or friction block" 13 (Flg. 4)in each of said notches presses upon thetrunnion 12 therein. A spring.plate 14 ateach side of the block 12 seats upon the upwardly extendedend of the correspondingblock 13 and, by means ofpre'ssure appliedthereto byscrews 15, causes the block \13 to bear with the desiredpressure upon the trunnion 12 in order to hold the block -11 in itsselected adjustments. That is, the upper endof the block 11 may be swungforwardly or rearwardly to a desired adjustment and retained in suchadjustment by Ipressureof the blocks 13 upon the trunnions12, but willper- ,mitthe block 11'to be forced from one adjust ment to another. Aspindle 16 is screwed in.

" the upperend of each of the. blocks 11and the length of each of saidspindles above the corresponding block 11 may be varied as re-" quiredto accommodate the machine for work upon shoes of'different sizes. Thatis, for a work upon shoesof small sizes, the spindles 16 will beadjusted to extend a greater distance above the blocks 11 than for workupon shoes of large sizes. i A gage orclamping nut 17 is threadedupon-eachof the spindles 16 and may be turned thereon to the pofitiondesired -to obtain the desired adjustment of the spindle 16 and toprevent accidental turning of said spindle.

' the course of manufacture is mounted for operation of this machine.-As there shown, the

Fig. 2 showsthe mannerin which a shoeiil shoe 18 ison its last 19. therear end of which ing block in proper adjustment.

1 this, a will be seen that theshoe "is placed.

upon the support upside down, the toe extending rearwardly.

The support for the toe comprises a block 20 extending between saidflanges 8 and having a depending flange 21. A clampin'g boltper end ofthe toe supporting block 20 is provided with a head 25 which isappropriately dished to receive and support the toes of shoes havinglasts therein. In use. the head 25 is preferably covered with a piece ofchamois 26 or other appropriate material to prevent damage to the shoewhen the machine is operated.

Each iron 27 is supported by a vertically movable frame. Each framecomprises a pair of rods 28, a cross head 29 connecting said rods attheir upper ends, and a cross head 30 connectingthe lower ends of saidrods. The rods extend for sliding movements through the top 4 and thecross bars 3 are guided thereby.

supported by eachframe by means of a hanger 31 having pivotal connection32- with the structure of the iron so as to permit such movement of theiron as may be necessary for it to'press with equal pressure across theentire portion of the shoe upon which it is intended to operate. Eachiron is provided with an electric heater 33 of known constructionconnected with circuit wires 34 by which the current is supplied, thecurrent being controlled by any desired switch connections (not shown)Each rod 28 is encircled by a coiled spring 35. These springs 35 havetheir lowerends bearing upon the cross bar 3 and their upper endsagainstcollars 36 rigid on the rods'28, and thereby serves to supportthe iron frames 1n their highest elevation and to raise such framesafter each operation. Extent of upward movement of the iron frames. bythe springs 35 is limited by collars 37 on the rods 28 arranged to abutagainst the undersurface ofthe top 4. I

Each iron frame has operating connections.

. As shown, the operating connection for each frame comprises a'link 38extending downwar'dly from connection with the lower cross head 30 toconnection with the cylinder 39.

Each cylinder 39 encloses a spring- 40. A rod 41 extends into eachcylinder 39 through the. spring 40.there1n. .A pin 42 in connection withthe upper end of each of the rods 40 its.

One of the irons-27 is' constitutes an abutment for the upper end of thespring 40 and extends through slots 43 in the cylinder 39,thuspermitting expansion and contractionof the spring 40 within lininoopenings between the parts of'the shoe.

The frontend of each of the treadle levers 44 operates with-in; a guide46 provided with latchte'eth 47 for engagement with a part 48 on thelever 44. to hold the lever 44 down so long as desired.

The lower end of the rod 40 is'connect-.

The lever 44 is capable of suflicient lateral oscillation toefi'ectengage' ment and disengagement thereof with respect to the latchteeth 47 In operation, the shoe is applied as shown 4 (Fig. 2) and asherein described with the last upon the'spindle 16and the toe of theshoe resting upon the non-abrasive cover 26 in order-t0 present thebottom of the shoe having the creased folded edges toward the iron 27.Then, .the treadle 44 is operated to press the iron with the desireddegree of pressure against that part of the shoe presented for operationof the iron thereon with the result that the parts are smoothed and theadhesive substance is caused to form a smooth surface so that, when theshoe is finishe'd, the parts present smooth sui faces against eachother. The machine is capable of easy and rapid operation and maybeconstructed economic-ally. The construction and relationship of thecooperative elements of the machine may be varied within equivalentlimits without departure from the nature and principle of the invention.
